This adds an initial configuration for staging. Note that we are doing
this ahead of having the full infrastructure in all 3 DCs. So this
this will result in some cross-DC writes for now (e.g. we have a single cache in
IAD). We'll correct this as the infrastructure becomes available.
We'll also run jobs on every app server, until we split them out to
separate instances.
